Flashcards in Photosynthesis Deck (10):
0

Autotroph

Create their own energy using light or chemical energy(chemosynthetic bacteria).

1

Heterotroph

Obtain their energy from the foods they consume.

2

Thylakoid

Coin shaped compartments.

3

Granum

A stack of Thylakoids.

4

Stroma

The space outside the Granum.

5

Chloroplast

The organelles where photosynthesis takes place.

6

Chlorophyll

A molecule in chloroplasts that absorb some of the energy in light. Chlorophyll does not absorb green light.

7

Light Dependent Reaction

Chlorophyll absorbs energy from sunlight,The energy is broken down in the thylakoids membrane. H2O molecules are broken down and O2 is released. Energy is transformed into ATP.

8

Light Independent Reactions

Use energy from Light dependent reactions to make sugars. Happens in the stromas of chloroplasts. CO2 is used to build larger molecules. Glucose is formed.

9

Chemosynthesis

The process by which some organisms use chemical energy instead of light energy.
